It's based on the installed fonts on your computer, so why not list all of them?
If only there were a way to determine installed fonts, but sadly, Javascript does not have that capability. It's possible to loop through known font names to determine the availability of a font within the browser, but that list isn't exhaustive. You can only detect the fonts that you choose to test for.

this.s.style.fontSize = "72px";
this.s.innerHTML = "mmmmmmmmmmlil";
this.h.appendChild(this.d);
